What the dual overload rating means for your drive selection
The 6SL3210-1PE14-3AL0 is a SINAMICS G120 PM240-2 power module rated for 1.1 kW under high overload (HO) and 1.5 kW under low overload (LO), with a built-in Class A EMC filter and integrated braking chopper. The HO rating delivers 200% current for 3 seconds, 150% for 57 seconds, and 100% for 240 seconds at 0 to +50 °C ambient — this is the spec to use when sizing for a constant-torque load like a conveyor or positive-displacement pump that needs short bursts of peak torque. The LO rating (150% for 3 s, 110% for 57 s, 100% for 240 s) applies at 0 to +40 °C and suits variable-torque loads such as centrifugal fans or pumps where peak demand is lower. The built-in braking chopper means you can add an external braking resistor for vertical loads or rapid deceleration profiles without an add-on module.
Integration notes for the panel builder
The module ships without a control unit or operator panel — you supply a separate CU (e.g., CU240E-2 or CU250S-2) that mounts directly onto the PM240-2. The FSA frame measures 196 x 73 x 165 mm (HxWxD) and is rated IP20, so it requires enclosure protection against dust and moisture. The built-in Class A filter covers conducted emissions for the 380–480 VAC supply; if your installation requires Class B (residential/commercial) limits, an external filter is needed upstream. The integrated braking chopper saves panel space and wiring compared to a separate braking module, but verify the resistor selection against the application's duty cycle.
